## Create Remote Connections through OPC-UA

### Simplify COM Connections

The OPC-COM Tunneller module eliminates many difficulties associated with establishing remote OPC-COM connections. The OPC-COM Tunneller module exposes OPC-COM connections to Ignition's OPC-UA server, allowing you to easily access them over the network and eliminate the need to use a Remote DCOM connection.

### Modernize COM Servers

Ignition manages the OPC-COM connection in the context of the OPC-UA standard resulting in easier access over the network, eliminating the need to establish remote DCOM connections, and incorporating the security benefits of the TCP standard such as authentication and encryption.
